Abstract:

One of the principal research themes of the supercritical fluid research group within the Centre of Separation Science and Technology (SST) at the North-West University (Potchefstroom Campus) is botanical extraction. The group produces botanical extracts from locally cultivated plants which contain substances (essential oils, natural waxes) relevant to the food, flavour, pharmaceutical, medical and cosmetic industries while utilising the advantages of sc-C& extraction over traditional steam distillation and solvent e~traction.'.~ In this study, which represents a contribution to a series of bo

Abstract:

Phenolic compounds, ubiquitous in plants, are of considerable interest and are increasingly becoming a subject of intensive research due to their bioactive properties such as antioxidant, antimicrobial, anti-mutagenic, anti-viral and anti-inflammatory activity. The objective of this research was to determine the antioxidant activity of extracts from selected plant materials, namely Caesalpinia spinosa, Perilla frutescens, Artemisia annua and Viola wittrockiana Gams. Plant material extracts were studied by in vitro methods, such as Total Phenolic Content, the measurement of scavenging capacity

Abstract:

Present days lifestyles increase the number of free radicals in our body and predispose people to oxidative stress, responsible for the development of several diseases as well as aging.

Its calyces contain anthocyanins, responsible for the antioxidant activity reported for the extracts. Moringa oleifera Lam. belongs to the Moringaceae family. Its antioxidant properties are mainly attributed to its phenolic compounds and,

Recent researches has suggested that alpha-eleostearic acid (α-ESA) in WBM was regarded as the most important compound of anti-inflammation. α-ESA is a ligand of peroxisome proliferator-activated receptor β (PPARβ). PPARβ can inhibit the production of cytokines by the inhibition of the degradation of IκB when it
